Also the encoding settings can change the size (for example xmediarecode didn't use same settings as default cli, file size was >2x the size). Container overhead can be that large (Check the elementary stream if you're doing that). And for a simple gradient, it is lossless (You can re-encode with CRF1 and PSNR is infinity)īe careful about just looking at the "filesize" only especially when it's just 1 frame, ~5Kb. "Lossless mode" isn't as widely supported in other programs, NLE's etc. Could you still please post your 10bit gradient test video here ? It's easy enough, even for beginners, to measure filesize and check for 10bit output in MediaInfo.Īlso why not use the encoder Lossless mode (x265 -lossless, x264 crf=0) ? I check end to end tests for various workflows (e.g. OK, I can imagine that the difficulty may in fact be analyzing the result rather than generating a gradient. Note on "real" content, the "ballooning" size won't be so drastic, but it's still suboptimal if you start with 10bit content Handbrake output >10x the size mainly because of the dithering, and gaps in the data (0,4,8) when you examine it. Handbrake "10bit" 2nd generation x265 crf 1 76kb Handbrake "10bit" 2nd generation x264 crf 1 70kb Xmediarecode 10bit x264 2nd generation crf 1 (same settings) 5kb ![]() X264cli 10bit 2nd generation crf 1 5kb (output PSNR actually lossless CRF1) I think some GUI's like staxrip canĠ-1023 gradient original produced at crf1 5kb Xmedia can preserve 10bit if you set it up correctly but I see no way of preserving the HDR metadata automatically. When you test - it dithers the intermediate stage (functions like noise to "hide" the banding), so it doesn't look as bad on a gradient as no dither - but the filesize balloons up because of the dithering Handbrake/vidcoder definitely uses an 8bit intermediate stage this is well documented. If there is an 8bit step, you will get gaps in the data such as 0,4,8, instead of 0,1,2,3,4,6,7,8, which of course results in more banding, less accuracy, worse compression When the process is complete, click on the " Download MP4" button to save the compressed file to local drive.You can test it with a 10bit gradient. You have to be patient for the conversion. Now, press " Compress Now!" button to upload and reduce video size to 5MB online. Choose " Target a file size (MB)" in the " Compression Method" drop-down list. Then click on " Gear" button to open " Advanced Options (Optional)" window. It even allows you to upload a video file from Dropbox, Google Drive, or an existing online URL. Press " Choose Files" button or just drag & drop a video file from your computer or other devices to the dotted box area. Open your preferred web browser and go to the FreeConverter website: It's easy to use and convenient, but it has a file size limitation and will spend much more time on the uploading and compressing process. It is a free online tool that can compress video to 5MB or less directly in your web browser. If you don't want to download any software, you can use a free online video compressor tool like FreeConverter. Finally, hit the green " Encode" button on the top bar to start 5MB video compressing process. Designate a destination folder to save the compressed video file and name it. A stager can change other parameters at will. Select " Target size (MB)" option and enter a value less than 5MB. Switch to " Video Encoding" tab and head over to " Quality" section. Go to " Container" tab and select " MP4" as the export video format. Click on the " Gear" icon next to the video name to open a new window. You're recommended to choose 720p or a lower resolution. Open the drop-down list of " Encoding settings" to choose a preset. ![]() Run VidCoder, go to " Open source" > " Open Video File" to add your source video. NET 6 Desktop Runtime is required to make it work. Download VidCoder Installer or Portable from official website. In order to compress a video to 5MB or less using VidCoder, follow these steps. It's super easy to use and can do just about anything you need it to. Personally, I'd say you gotta give VidCoder a shot. And get this, it can handle all sorts of video formats and even lets you tweak the advanced compression settings like video bit rate, resolution, and audio quality. VidCoder is an awesome, free and open-source software that lets you shrink your videos down to 5MB or less. ![]()
